genkit 0.9.0

A type-safe Dart client library for calling Google Genkit flows with streaming support, authentication, and comprehensive error handling.

0.9.0

• Made fromResponse and fromStreamChunk optional in defineRemoteAction. If not provided, the response and stream chunks will be dynamic objects decoded from JSON, instead of requiring a typed conversion function.

0.8.0

• BREAKING CHANGE: The .stream() method now returns an ActionStream instead of a FlowStreamResponse record. ActionStream is a Stream that provides two ways to access the flow's final, non-streamed response:

  • onResult: A Future that completes with the result. This is the recommended approach. It will complete with a GenkitException if the stream terminates with an error or is cancelled.
  • result: A synchronous getter that should only be used after the stream is fully consumed. It will throw a GenkitException if the stream is not consumed, terminates with an error or is cancelled.

  Migration: Code that previously looked like this:

  final (:stream, :response) = myAction.stream(input: ...);
  await for (final chunk in stream) {
    // ...
  }
  final finalResult = await response;
  

  Should be updated to use onResult:

  final stream = myAction.stream(input: ...);
  await for (final chunk in stream) {
    // ...
  }
  final finalResult = await stream.onResult;
  // or
  final finalResult = stream.result;
  

0.7.0

• BREAKING CHANGE: The package has been renamed from package:genkit/genkit.dart to package:genkit/client.dart. You will need to update your import statements.
• BREAKING CHANGE: The response future returned by the .stream() method is now nullable (Future<O?>). This change supports improved error handling and cancellation.
• Improved Error Handling: Errors occurring on the server during a stream are now thrown by the stream itself. This allows you to catch exceptions directly within a try/catch block surrounding an await for loop.

0.6.0

• Added standard Genkit data classes for working with generative models, including GenerateResponse, Message, and Part types.
• Added helper getters like .text and .media for easier data extraction.
